The invention belongs to the technical field of ship equipment, and discloses a cargo oil pump sweeping system and a ship, the cargo oil pump sweeping system comprises a cargo oil header pipe, a cargo oil branch pipe and a sweeping suction port, a cargo oil pump is installed on the cargo oil header pipe, and the cargo oil pump sweeping system further comprises a sweeping branch pipe, a sweeping line header pipe, a first sweeping line branch pipe, a negative pressure system and a purging pipeline. One end of the sweeping branch pipe extends into the suction well, the other end of the sweeping branch pipe is connected with the cargo oil branch pipe, and a sweeping valve is arranged on the sweeping branch pipe; one end of the first line sweeping branch pipe is connected with the cargo oil branch pipe, the other end of the first line sweeping branch pipe is connected with the line sweeping header pipe, and a first line sweeping valve is arranged on the first line sweeping branch pipe; the negative pressure system is connected with the cargo oil header pipe and can provide negative pressure for the cargo oil header pipe; the purging pipeline is connected with the cargo oil header pipe and can provide compressed gas for the cargo oil header pipe, and a purging valve is arranged on the purging pipeline. The cargo oil pump sweeping system can deeply purge raffinate of a suction well in a cargo oil tank and pipeline raffinate in a cargo oil header pipe and a cargo oil branch pipe, and minimization of sweeping residual volume is achieved.

    本发明属于船舶设备技术领域,公开了一种货油泵扫舱系统和船舶,货油泵扫舱系统,包括货油总管、货油支管和扫舱吸口,货油总管上安装有货油泵,货油泵扫舱系统还包括扫舱支管、扫线总管、第一扫线支管、负压系统和吹扫管线。扫舱支管一端伸入吸井,另一端与货油支管连接,扫舱支管上设置有扫舱阀;第一扫线支管一端与货油支管连接,另一端与扫线总管连接,第一扫线支管上设置有第一扫线阀;负压系统与货油总管连接,能向货油总管提供负压;吹扫管线与货油总管连接,能向货油总管提供压缩气体,吹扫管线上设置有吹扫阀。该货油泵扫舱系统能对货油舱内吸井的残液以及货油总管、货油支管内管路残液进行深度吹扫,实现了扫舱残余量最小化。
